After the weakening of the Byzantine Empire and the Bulgarian Empire in the middle and late 13th century, most of the territory of modern-day Albania became part of Serbia. Firstly, as part of Serbian Grand Principality and later as part of Serbian Empire. The southern part was governed by the semi-independent, Serbian-ruled Despotate of Epirus. Between 1272 and 1368, some areas of the modern-day state were also ruled by the Angevins as the Kingdom of Albania. In the late 14th century, Albanian Principalities were created throughout Albania.
